After knee surgery, your trainer tells you to return to your jogging program slowly. He suggests jogging for 12 minutes each day for the first week. Each week thereafter, he suggests that you increase that time by 6 minutes per day. How many weeks will it be before you are up to jogging 60 minutes per day?
Answer:
8 weeks
Step-by-step explanation:
1. Write out the equation
12+6x=60
2. Subtract 12 from both sides
6x = 48
isolate the variable (divide 6 on both sides)
x= 8
How can you solve an equation with a variable on both sides? Complete the explanation.
You can solve the equation by using ____ operations to get the variable terms on one side of the equal sign and the constant terms on the ____ side. Then ____ both sides by the

Point A is rotated 90 degrees counterclockwise around point C to form the image A'. Select three true statements based on the given information.
Answer:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
Then the correct statements are:
A' lies on a circle centered at point C with radius AC
This is by definition.
m∠ACA' = 90°
This is because A is rotated 90° around C to form the image A', then the measure must be 90°.
AC = A'C
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.
Answer:
AC = A'C
A' lies on a circle centered at point C with radius AC
m∠ACA' = 90°
Step-by-step explanation:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.

A personnel manager has found that, historically, the scores on aptitude tests given to applicants for entry-level positions follow a normal distribution with standard deviation 21.73 points. A random sample of 14 test scores from the current group of applicants had a mean score of 74.57 points. Based on these sample results, a statistician found for the population mean a confidence interval extending from 65.7425 to 83.3975 points. Find the confidence level of this interval. Round off your answer to two decimal places.
Answer:
The value is [tex]C = 85\%[/tex]
Step-by-step explanation:
From the question we are told that
The standard deviation is [tex]\sigma = 21.73[/tex]
The sample size is n = 14
The mean score is [tex]\= x = 74.57[/tex]
The confidence interval is 65.7425 to 83.3975
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 14 -1[/tex]
=> [tex]df = 13[/tex]
Generally the margin of error is mathematically evaluated as
[tex]E = \frac{83.3975 -65.7425 }{2}[/tex]
=> [tex]E = 8.828[/tex]
Generally this margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2} , df} * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]8.828 = t_{\frac{\alpha }{2} , df} * \frac{21.73 }{\sqrt{14} }[/tex]
=> [tex]t_{\frac{\alpha }{2} , df} = 1.520[/tex]
From the t distribution table the probability of [tex]( t> 1.520 )[/tex] at a degree of freedom of 13 is
[tex]\frac{\alpha }{2} = P( t > 1.52 ) = 0.076[/tex]
=> [tex]\alpha = 2 * 0.076[/tex]
=> [tex]\alpha = 1.52[/tex]
So the confidence level is evaluated as
[tex]C = 1- \alpha[/tex]
=> [tex]C = 1- 0.152[/tex]
=> [tex]C = 0.85[/tex]
Converting to percentage
=> [tex]C = 0.85 * 100[/tex]
=> [tex]C = 85\%[/tex]

Question 5 options:
A)

The distance of the farmer to the tractor would be gotten by subtracting the coordinate of the farmer from that of the point of the tractor.
What is distance?The definition of distance in mathematics is the shortest space that lies between two different points.
Given that the points that the farmer and the tractor are standing on are unspecified, the distance would be point of farmer subtracted from that of the tractor.

C. 0.7
D. 0.8
Answer:
C
Step-by-step explanation:
I hope this helps!!!!
The best estimate of the fraction 29/40 would be; 0.7
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the decimal that best best estimate of the fraction 29/40
A negative divided by a negative is positive, then;
29/40 = 0.72

factor 49x^2-7^2
and please explain how
Answer:
[tex]49x^2-7^2=49(x-1)(x+1)[/tex]
Step-by-step explanation:
Factoring
We need to recall this property of binomials:
[tex](a-b)(a+b)= a^2-b^2[/tex]
It allows us to factor the difference between two squares as follows.
[tex]a^2-b^2=(a-b)(a+b)[/tex]
The given expression is
[tex]49x^2-7^2[/tex]
Comparing with the above expression:
[tex]a^2=49x^2[/tex]
Taking square root:
[tex]a = 7x[/tex]
[tex]b^2=7^2[/tex]
Taking square root:
b=7
Factoring:
[tex]49x^2-7^2=(7x-7)(7x+7)[/tex]
Now we can see each factor can be taken out the common factor 7:
[tex]49x^2-7^2=7(x-1)*7(x+1)[/tex]
Multiplying:
[tex]\boxed{49x^2-7^2=49(x-1)(x+1)}[/tex]
A company plans to sell a new type of vacuum cleaner for $280 each. The company’s financial planner estimates that the cost, y, of manufacturing the vacuum cleaners is a quadratic function with a y-intercept of 11,000 and a vertex of (500, 24,000). Which system of equations can be used to determine how many vacuums must be sold for the company to make a profit?

Answer:
StartLayout Enlarged Left-Brace 1st Row y = 280 x 2nd Row y = negative 0.052 (x minus 500) squared + 24,000 EndLayout
Step-by-step explanation:
Given that:
Cost per cleaner = $280
The cost of x vacuum cleaners will be :
Cost per cleaner * number of cleaners
$280 * x
= $280x
The general vertex firm equation :
y-k = a(x-h)^2
Vertex = (500, 24000) ; Vertex = (h, k)
h = 500 ; k =24000 y= 11000, x = 0
y intercept = 11000
Plugging the values :
11000 - 24000 = a(0 - 500)^2
- 13000 = a(-500)^2
-13000 = a * 250000
a = - 13000 / 250000
a = - 0.052
Hence,
y - 24000 = a(0 - 500)^2
y = - 0.052(0 - 500)^2 + 24000

Tom will need to offer additional collateral of C. $2,437.50 to borrow enough for his planned vacation.
What is collateral?Collateral refers to a valued property or financial security offered by the borrower to the lender to guarantee repayment of a loan.
Lenders sell collaterals when the borrowers fail to comply with their loan terms.
How is the additional collateral determined?Car's value = $3,500
Collateral value in percentage = 80%
Car's collateral value = $2,800 ($3,500 x 80%)
Planned cost of vacation = $4,750
Additional cost to meet vacation cost = $1,950 ($4,750 - $2,800)
Additional collateral value to meet target = $2,437.50 ($1,950/80%)
Total collateral that Tom needs to offer = $5,937.50 ($3,500 + $2,437.50)
80% of $5,937.50 = $4,750
Another way is to work with the planned cost and the collateral percentage offered by Tom's bank:
Planned cost of vacation = $4,750
Collateral value in percentage = 80%
Total collateral to be offered by Tom = $5,937.50 ($4,750/80%)
Car's collateral value = $3,500
Additional collateral value = $2,437.50 ($5,937.50 - $3,500)
Thus, Tom needs additional collateral of C. $2,437.50.

The heights of women aged 20 to 29 are approximately Normal with mean 64.3 inches and standard deviation 2.7 inches. Men the same age have mean height 69.9 inches with a standard deviation 3.1 inches. Describe in lay terms what information the z scores give that the original nonstandardized heights do not.
Answer:
In a lay term; The z-score gives us information concerning how many percentages of data lie between the given data interval. The z-score gives us an overview of the distance from the mean a data point is. In addition to that, it measures the degree of standard deviations below or above the population mean a raw score. We can place a z-score on a normal distribution curve.
Step-by-step explanation:
Given that:
Height of woman between age 20 -29 are approximately normal with:
population mean = 64.3 inches &;
standard deviation = 2.7
For men:
population mean = 69.9 inches
Standard deviation = 3.1 inches
In a lay term; The z-score gives us information concerning how many percentages of data lie between the given data interval. The z-score gives us an overview of the distance from the mean a data point is. In addition to that, it measures the degree of standard deviations below or above the population mean a raw score.
